COTTON-GIN.

SPECIFICATION forming part of Letters Patent No.311,001, dated January20,1885.

' Application filt d July I, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, ELI G. HORNE, of Jasper, in the county of Hamiltonand State of Florida, have invented certain new and useful Improvementsin Cotton-Gins, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

said bars and the frame of the gin.

in which similar letters of reference indicate corresponding parts inall the figures.

Figure l is a sectional side elevation of my improvement. Fig. 2 is arear elevation of the same, part being broken away. Fig. 3 is a planview of the same, part being broken away.

The object of this invention is to facilitate the ginning of cotton andprevent the fibers from being broken while passing through the machine.

' The invention comprises a cotton-gin constructed with a knife securedto its holding plate by screws, with its edge near the ginhing-cylinder,so as to separate the seeds from the fibers as the said fibers are drawnbetween the said cylinder and knife. The knife is secured to itsholding-plate by screws and seetional clamping-plates, so that the saidknife will be held firmly in place. The knife-holding plate is securedto the end frames of the gin by pivoted bracket-arms, clamping-bolts,and set-screws, whereby the said knife can be readily adjusted atanyidesired distance from the ginning-cylinder. At the rear ofthe knifeand cylinder are placed a vibrating bar and plate, supported by rodsfrom bars hinged'to the frame-arms, and provided with cams resting uponrollers pivoted to the end flanges of the ginning-cylinder, whereby thesaid bar and plate will be raised and lowered, to straighten the fibersand push back the seeds by the revolution of the said cylinder. The camsof the hinged bars are held down upon theirrollers by springs connectedwith the To the vibrating bar and plate is attached the inner edge of awire netting, hinged at its outer edge to a plate secured adj ustably totheframearms by screws, whereby the seeds are allowed to escape from themachine, and the said bar and plate can be adjusted to any desireddistance from the knife and cylinder, as will be hereinafter fullydescribed and claimed.

A represents the end frames of the machine, the lower parts of which areconnected by a crossbar, A.

B is the cylinder, which is made with flanges (3 upon its ends, and iscovered with strips, D,

'of leather applied to it spirally, as shown in Fig. 3. The flanged endsof the cylinder ,3 are placed in recesses in the tops of the frames A,and the journals of the said cylinder revolvein bearings E, attached tothe said frames.

One of the journals of the cylinder B projects, and to it is attached acone-pulley, F, to receive the driving-belt.

To the outer sides of the flanges O of the cylinder B are pivoted smallrollers G, upon which rest the cams H, formed upon or at taehed to theinner ends of the bars I, so that the said bars will have adownwardmovement as each roller G passes out from beneath the cams H, and anupward movement as the next rollers pass in beneath the said cams. Theouter ends of the bars I are hinged to the outer ends of theupwardlyinclined arms J, formed upon or attached to the rear side of theupper ends of the frames A. The cams H are held down upon the rollers Gby spiral springs K, the upper ends of which are attached to the hingedbars I, and their lower ends are attached to the inner sides of theframes A.

L is the knife for separating the seeds from the fiber. The knife Lrest-s against the holding-plate M, where it is clamped in place by thesectional plate N, secured to the holdingplate M by the screws 0, andreduced or cut away on one side intermediately of its upper and lowerends to remove it thereat from c0ntact with the knife,whereby saidsection-plate may be adjusted or deflected at different points along itssurface upon the knife, to cause the latter to bear upon the cylinderwhere worn away or uneven.

To the lower corners of the holding-plate M are attached arms orbracketsP, the lower ends of which are pivoted to the frames Aby thebolts Q, so that the said holding-plate M and the knife L can beadjusted toward or from the cylinder 13. The holding-plate M is securedin place when adjusted by screw-bolts R, which pass through slots in theend frames, A, and screw into the ends of the said plate M, and whichare held against the outward pressure of the knife L by set-screws S,passing in through the rear edges of the end frames, A, and restingagainst the sides of the screwbolts It. The ginning-knife L is raisedand lowered by means of set-screws L, which passv up through a flange,M, upon the lower edge of the holding-plate M, and rest against thelower edge of the saidknife L. The rear side of the upper edge of theginning-knife L is beveled, and against the said bevel rests the plateT, attached to the forward side of the bar U. To the upper sides of theends of the bar Uare hiugedthe lower ends of the rods V, the upper endsof which are secured by nuts or other suitable means to the pins WV,supported in curved bail-shaped brackets V, having lateral or horizontalarms entering and secured to the bars I, and its plate T will be raisedand lowered by and with the said cambars I. The upper side of the bar Uis beveled, and to it is attached the forward edge of a wire-netting, X,the meshes of which are of such a size as to allow the cottonseeds topass through them freely. The rear edge of the wire-netting-X is hingedto the forward edge of the plate Y, so that the bar U and plate T canmove up and down freely. The plate Y is placed between the arms J, andits ends are secured to the said arms by screws Z, which pass throughslots in the said arms and screw into the said ends, so that the plate Ycan be readily adjusted to bring the bar U and plate T to any desireddistance from the knife L. The hopper or chute through which the cottonis fed to the machine is not shown in the drawings, as there is nothingnew in its construction. Vith this construction, as the cotton is drawnby the revolution of the cylinder 13 between the said cylinder and theknife L, the up and down movements of the bar U and plate T raise thecotton, and thus straighten the fibers, so that the said fibers will bedrawn through longitudinally, and will thus be less liable to be brokenand shortened than when the ordinary gin is used. At the same time theknife L prevents the seeds from passing through with the fibers, and thebar U and plate T in their upward movements push back the seeds, andthus assist in separating them from the fibers, the said seeds escapingfrom the machine through the wire-netting X.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cotton-gin, the combination, with the knife and itsholding-plate, of the sectional clamping-plate provided with adjustingor holding screws, and having one side cut away or reducedintermediately of its upper and lower ends, and the knife adjustingscrews passed through the knife-holding plate and the sectionalclamping-plate and bearing against the lower edge of the knife,substantially as and for the purpose set forth.

2. In a cotton-gin, the combination, with the knife and holding-plate,of the pivoted bracket-arms and screws passing through the base of saidplate and bearing against the low er edge of said knife for adjustingand holding the plate, substantially as herein shown and described,whereby the knife can be readily adjusted to any desired distance fromthe ginning-cylinder, as set forth.

3. In a cotton-gin, the combination, with the knife, of theholding-plate, the pivoted brackets or arms connected to'said plate, theadjusting screw-bolts connecting with said plate, and the holding-screwsbearing against the sides of said bolts, substantially as and for thepurpose specified.

4. In a cottongin, the combination, with the cylinder and knife, of thevibrating bar and plate U T, the hinged screen X, con nected to saidbar, the adj listing-plate Y, and a supporting and operating mechanism,sub

stantially as herein shown and described,

whereby the cotton fibers are straightened and the seeds are pushedback, as set forth.

5. In a cotton-gin, the cylinder having the flanges O, the arms J of theframe, and the bar and plate U T, in combination with the rods V,connected to said bar U, pivotal pins XV, curved bail-shaped brackets W,having lat eral arms, the rollers G, the cams H, and the hinged bars I,substantially as and for the purpose set forth.

6. In a cotton-gin, the combination, with the arms Jof the frame and thevibrating bar and plate U T, of the hinged wire-netting X, theadjustable plate Y, and its fasteningscrews Z, substantially as hereinshown and described, whereby the seeds are allowed to escape from thegin, and the said bar and plate can be adjusted at any desired distancefrom the knife, as set forth.
